The usage method of intelligent dynamic sealed liquid storage tank with flexible capsule

Abstract

The invention relates to an intelligent dynamic sealing liquid storage tank with a flexible capsule and a using method of the intelligent dynamic sealing liquid storage tank with the flexible capsule. A liquid inlet and a venting port are formed in the upper portion of the liquid storage tank, a liquid inlet solenoid valve is arranged on the liquid inlet, a vent valve is arranged on the venting port, and a liquid outlet is formed in the lower portion of the liquid storage tank. A liquid outlet solenoid valve and on-line moisture detectors are sequentially arranged on the liquid outlet in the liquid outlet direction. An air tube and an electric contact liquid level meter are further arranged on the liquid storage tank, the flexible capsule is arranged in the liquid storage tank, and the surface of the capsule is surrounded by liquid. An inner cavity of the flexible capsule is communicated with outside atmosphere through the air tube, and the liquid inlet solenoid valve, the liquid outlet solenoid valve, the on-line moisture detectors and the electric contain liquid level meter are electrically connected to a control module. Due to the fact that the inner cavity of the flexible capsule is communicated with the outside atmosphere through the air tube, the breathing effect of the flexible capsule plays a role in compensating and balancing volume changes caused by changes of the liquid level in the liquid storage tank, and dynamic sealing is achieved.

Description

technical field [0001] The invention relates to an intelligent dynamic sealed liquid storage tank with a flexible capsule and a using method thereof. Background technique [0002] The physical and chemical properties of transformer oil are relatively stable at normal temperature and pressure, and the density is about 0.86 (there will be slight differences between different origins and different oil types). The electrical performance of the oil is greatly affected, and the presence of water in the oil also aggravates the deterioration of the oil. Transformer oil is prone to moisture, especially in rainy season or humid weather. If the seal is not good, dozens of tons of oil will be damp in a few days and need to be reprocessed before use. Therefore, a sealing method is adopted to prevent the intrusion of moisture, moisture, air, impurities, etc. It is the most important factor to ensure the quality of transformer oil storage. The traditional liquid storage methods mainly in...

Problems solved by technology

This storage method is the most common at present. Using this storage method is better than the first method, but it cannot be isolated from the air, and the hygroscopic packing saturated with moisture absorption needs to be replaced frequently.

[0005] The third type is storage in small oil barrels: 170kg standard barrels of transformer oil or other similar small oil barrels are usually sealed by tightening the gland, but the operation is cumbersome and time-consuming when adding and draining oil and handling a large amount of oil. And the labor intensity is high. At this time, the oil product is in contact with the outside air, which is easy to be affected by moisture, and it is easy to cause environmental pollution such as leakage, leakage, etc.

[0006] The above traditional storage methods of transformer oil do not have dynamic sealing function, and cannot isolate air and moisture during work, and cannot guarantee the quality of stored oil for a long time, safely and reliably
